Anyone have the same experience why the car is throwing these codes. My ride feels pretty much the same can't really feel a decline in performance. My guess would maybe be the o2 sensor is bank 2 but i'm not sure. Chime in please. Thanks in advance.

When my precat 02 went bad I got P2CAB and P2CA7 codes, I got it replaced within a week so I didn't bother checking AFRs and whatnot, but the car felt more or less OK. The day I took it in it was not a happy camper on cold start, didn't throw misfire codes but it was stumbling all over the place until it got warm.
